KGN -12 fixed metal-clad switchgear(short for switchgear as below) applies to 3.6~12KV,

3 phase AC 50/60Hz network for receiving and distributing power energy and also for control, monitor and protection.

It can be used in s ingle busbar, single busbar section system.

It is manufactured inaccordance with IEC62271-200 & GB3906 3~35KV AC Metal Enclosed Switchgear, DL404 Order Specification for Indoor AC HV Switchgear and so on.

It has reliable prevention function against false operation.

Q:definition: *Many electrical installations have a relatively high earth impedance. This may be due to the use of a local earth rod (TT systems), or to dry local ground conditions. These installations are dangerous and a safety risk if a live to earth fault current flows. Because earth impedance is high, 1. not enough current exists to trip a fuse or circuit breaker, so the condition persists uncleared indefinitely 2. the high impedance earth cannot keep the voltage of all exposed metal to a safe voltage, all such metalwork may rise to close to live conductor voltage. These dangers can be drastically reduced by the use of an ELCB or Residual-current device (RCD). The ELCB makes such installations much safer by cutting the power if these dangerous conditions occur. This approach to electrical safety is called EEBAD. In Britain EEBAD domestic installations became standard in the 1950s. In non-technical terms if a person touches something, typically a metal part on faulty electrical equipment, which is at a significant voltage relative to the earth, electrical current will flow through him/her to the earth. The current that flows is too small to trip an electrical fuse which could disconnect the electricity supply, but can be enough to kill. An ELCB detects even a small current to earth (Earth Leakage) and disconnects the equipment (Circuit Breaker). Go through the source links. Also read and seach for residual current device.

Q:I would like to start testing and reconditioning some electrical equipment and I'm wondering what device or devices I can use to out put a specified voltage/amperage either AC or DC.for instance I have an electric motor that needs 5v 20amps, and I require a device that would allow me to plug into a wall outlet and regulate the voltage and amps to the proper levels for testing this device.hopefully that makes sense, thanks: if its AC you can use a variable speed drive or VoltPac but if ur talking DC then u need an adjustable power supply. You can build one or you can probably buy a more stable unit if you have the money to spend.

Q:Assuming that it is safe to do so as far as people not getting hurt, will it damage the electrical equipment?: Some appliances like for instance your computer require a shutdown routine in sequence to be happy. Your computer will complain and cry if you suddenly pull the power and the disk or data may be damaged by sudden disconnect but usually nothing major will happen except loss of your photo or video or term paper. most of the hardware must withstand sudden shutdown but it is not a good routine to practice.

Q:does it or not losers??: Yes

Q:Hi!Is there an NEC section which addresses the following kitchen design? I'm working with an apartment complex and they've designed each unit's breaker box to be located directly over the stove top burners. Something just sounds real bad here - but, perhaps I worry about things melting when water is brought to a boil or the oven is at 450 F for an hour or so and the vent for the oven is directly through a back burner. [The door for the breaker box just clears the top of the stove top.]Thank you!!: 1Shawn Michaels Iron Man Match two. Undertaker (C) Last Ride Match three. Randy Orton (C) Street Fight four.

Q:i dont understand this, every surge protector claims to protect phone lines from surges but why?: The surge protection works via combating the skill surges which could take place whilst a line is hit via lightning, or whilst skill unexpectedly is going off. In a worse case project you're able to desire to burn out ALL electric powered home equipment that are linked, and in spite of small surges your computer could desire to be broken. relatively a solid concept to have the computer secure, regardless of in case you haven't any longer something secure.

Q:I am assuming that the car is running when the items are being used.: Disclaimer: i don't understand something approximately autos! I recall whilst i became into youthful, we've been using abode at evening and each and all the lighting fixtures fixtures in my mom's van started out to dim. We made it very almost each and each of ways abode (we've been a lengthy techniques from abode) in the past the van died. It seems that it became into the alternator. You did not say if the automobile will start up back, my guess is that it will not. back, i don't understand something approximately autos, so it could be the battery, yet my guess is the alternator. solid success!

Q:???I recently went into a century tel building and was VERY interested. Does that have anything to do with what an electrical intrumentation technician does? If not please explain to me the difference between some one that is an electrical instrumentation technician would do, and what someone that works at century tel would do. I know this is a lot but Im planning for a major, and after that a career.Thanks!!!: You don't have the necessary qualifications for either immigration or temporary employment visa to Canada (or the US, for that matter). Instrumentation techs lack sufficient education and skill levels. You would need at least at bachelors, preferably masters, degree in Instrumentation Engineering to start with.

Q:I plan to major in electrical engineering. I wanted to know if the stuff I learn there will allow me to do things like fix machines and stuff.I picked this major because I wanted something I can use at home: I would suggest if you want to fix things at home you attend a technical school that trains electricians. Then you can become certified or licensed and earn a living. You might also want to get a degree in mechanical engineering so you can repair your plumbing. There are lots of skills an electrician has that are not taught in engineering school. If you have a degree in mechanical engineering that doesn't mean you are qualified to tear down an engine and rebuild it. I am not trying to make fun of your question but you should choose a discipline that suits your abilities and interests.
